The following example shows all zones beginning with A, B, or C:
switch:admin> zoneshow "[A-C]*"
zone: Blue_zone 1,1; array1; 1,2; array2
zone: Bobs_zone 4,5; 4,6; 4,7; 4,8; 4,9
If no parameters are specified, the entire zone database (both the defined and effective
configuration) is displayed.

Default zoning mode

The default zoning mode controls device access if zoning is not implemented or if there is no effective zone
configuration. The default zoning mode has two options:
• All Access—All devices within the fabric can communicate with all other devices.
• No Access—Devices in the fabric cannot access any other device in the fabric.
The default zone mode applies to the entire fabric, regardless of switch model.
Typically, when you issue the cfgDisable command in a large fabric with thousands of devices, the
name server indicates to all hosts that they can communicate with each other. In fact, each host can receive
an enormous list of PIDs, and ultimately cause other hosts to run out of memory or crash. To ensure that all
devices in a fabric do not see each other during a cfgDisable operation, set the default zoning mode to
No Access.
NOTE: If you want to use Admin Domains, you must set the default zoning mode to No Access prior to
setting up the Admin Domains. You cannot change the default zoning mode to All Access if user-specified
Admin Domains are present in the fabric.

Setting the default zoning mode

1. Connect to the switch and log in as admin.
2. Enter the cfgActvShow command to view the current zone configuration.
3. Enter the defZone
progress) and prevents all Nx_Ports from communicating with each other.
4. Enter either the cfgSave, cfgEnable, or cfgDisable command to commit the change and
distribute it to the fabric. The change will not be committed and distributed across the fabric if you do
not enter one of these commands.
After setting the default zone access mode to noaccess, subsequent use of the cfgDisable command
performs the equivalent of the cfgEnable "d_efault_Cfg" command.

Viewing the current default zone access mode

To view the current default zone access mode:
1. Connect to the switch and log in as admin.
2. Enter the defZone
NOTE: IIf you performed a firmware download of an older release, then the current default zone access
state will appear as it did prior to the download. For example, if the default zoning mode was No Access
before the download, it will remain as No Access afterward.
